Tech: Infrared Sensor

LI: To use Infrared sensors in mBot robots to follow the track.



This week for our year 8 robotics session we went to Tamaki College and worked with Ms. Ferguson. The above picture showcases me coding the commands for the infrared sensor in the computer. We first learned about the difference between ultrasonic and infrared light. Ultrasonic light is the type of light which contains the blue shades of the seven colors in the white light where as infrared light is the type of light which contains the red shades of the seven colors in the rainbow. Then we learned about the binary numbers used as a method to add them in our codes. The two numbers help the mBot robot to differentiate between the black tracks and the white background. Once we got the correct codes and then uploaded to the robot we try it on the track. I was so very happy when it worked as it took an average of seven tries to get the correct code. I received a lot of help from Florence, Haylee and Ms. Ferguson. I gained a lot of information on the two different types of sensors in robots after going to my Tech class with Ms. Ferguson.
